Fatented July 11, 1933 TES UNITED STA CHARLES A. OLSON, OF GENEVA, ILLINOIS, AS SIGNOR TO CRANE 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS RADIATOR with Application filed Gctober 9,

This invention relates to a radiator, more particularly to that-class popularly known as the concealed type.

In connection with the beautifying of the interior of apartments and residences, there is an increasing tendency to place radiators in concealed locations, as for example, behind grilles, partitions, under radiator covers, and the like.

At the same time such concealment assists in providing for more floorspace within the room without detracting from the appearance.

One of the principal objects of this invention is to provide for a radiator with integral fins, which are so arranged as to give the maximum heat transmission surface, having in mind, such important attributes as convection, conduction and radiation.

A still further aim is to provide a radiator of this type in which the free passage of air along the fin arrangement will be facilitated.

Another object of this invention is to pro- 2 5 vide a radiator of such design and construction as can be economically manufactured particularly considering such items as casting and machining.

Another object is to provide a radiator in which easy cleansibility thereof is expedited.

More of the objects will be apparent and a better understandingwill be had of this invention from a consideration of the following description given in connection with the drawings, in which Fig. 1 is a plan View or top view of the radiator.

Fig. 2 is the side view of the radiator showing one form of radiator using a multiple port arrangement withintegral cast fins.

Fig. 3 is an end View showing the same radiator installed behind the conventional r grille work in the room.

Fig. 4 is an enlarged broken section taken at the inlet (1) in Fig. 2, showing one form of entry used for the heat transmission fluid, whether it be steam or hot water.

In the drawings (Figs. 2 and 3) an eleva- INTEGRAL FINS 1931. Serial No. 567,900.

tion and also an end view respectively of a three tube or column radiator is illustrated, although it is obvious that the number of columns and the number of sections, and the height of the sections is immaterialinsofar as this invention is concerned. In Fi 1, I employ the same conventional inlet (1) for filling the section with the liquid heat ing medium. The fins (2) are preferable in unbroken file arrangement although in some to instances it may be desirable to. arrange them in staggered fashion. The pattern is preferably split on the centerline shown in Fig. 1, for the purpose of drawing the pattern from the mold. The fins are therefore made, with sufficient draft or taper as shown at At the same time it facilitates greater strength. It is essential that the fins be made withgreater thickness at their bases to prevent breakage. Any num- 7ober of sections may be used and connected up by the usual right and left hand hexagon nipples depending upon the size of the room and the heating capacities desired. I make use of the square or slightly rectangu- 7'5 lar shaped fin in this transverse section as shown at (5) in Fig. 3. Similarly, I make use of an elliptical shaped column as shown at (6), although it is obvious that these forms or shapes may be altered to suit conso ditions without detracting from the invention. I

In this construction I make use of another advantage, namely, that of an off-set shown H at (12) which results in being able to connect each adjoinin section with a minimum amount of space between them; this results in a hexagon nipple (4) being closely joined without a significant break in the assembled sections (13 and let), for example, it is ob vious that such off-set may be affected in minor changes of the construction shown.

The operation of a radiator using my principle is as follows: 1

Steam enters at the inlet (1) in Fig. 2, or 5:1 as shown in more detail in Fig. 4, thus filling the section and entering through the outlet into such section or sections as may be connected thereto. The bosses (7) in Fig. 1, and (8) in Fig. 3, are used as venting means for such air as may be trapped between during respective heating and cooling. An air valve not shown is usually tapped into the boss for this purpose.

In Fig. 3, I have shown the usual form of grille employed in a home for the purpose of housing this radiator, although this may be altered from the construction shown to suit the size and shape of the radiator and the conditions in the room. (9) in Fig. 3 is a metal deflector serving to project the heat of convection or radiation into the room through the grille (11).

Other advantages are apparent from the foregoing description and minor changes may be made in the details of construction and form without departing from the scope of this invention as defined in claims appended hereto.

I claim:

1. A radiator section comprising a pair of separate spaced headers, a plurality of integral independent tubes of elliptical cross sec tion, the minor axis of the said elliptical sections extending from the front to the back of the radiator, said tubes being integrally connected at their ends to said headers so as to provide communication between said headers, a plurality of solid radiating fins integral with and disposed transversely to said tubes, said radiating fins being substantially square in their transverse sections, connecting means at the end of each header providing for substantially continuous and unbroken heat transmitting surface when assembled with a radiator section similarly provided.

2. A radiator section comprising a pair of separate spaced headers, a plurality of integral independent tubes of elliptical cross section, the minor axis of said elliptical sections extending from the front to the back of the radiator with'the major axis thereof at right angles to said minor aXis, said tubes being integrally connected at their ends to said headers so as to provide communication between said headers, a plurality of solid radiating fins integral with and disposed transversely to said tubes, said radiating fins beingsubstantially square in their transverse sections, the length of such square being substantially equal to the length of the said major axis, connecting means at the end of each header providing for substantially continuous and unbroken heat transmitting surface when assembledwith a radiator section similarly provided.

In witness of the foregoing I affix my signature.

CHARLES A. OLSON.
